Railroad-chair



UNITED STATES PATENT OFFICE.

ISAAC B. HOWE, OF NORTHFIELD, VERMONT.

RAILROAD-CHAIR.

Specification of Letters Patent No. 24,639, dated July 5, 1859.

To all whom 'it may concern:

Be it known that I, I. B. HOWE, of Northfield, in the county ofWashington and State of Vermont, have invented a new and ImprovedJoint-Chair for Railroad-Rails, of which the following is a full, clear,and exact description, reference being had to the accompanying drawings,making part of this specification, in which- Figure l, is a plan; Fig.2, an elevation; Fig. 3, a section upon the line A, A, of Fig. l; Fig.4, a View ot' my chair detached.

My invention consists in a peculiar one lip chair in connection with afishing piece secured permanently to the sleepers and a method ofsecuring both chair and rail in place by a single bolt the whole soarranged that on withdrawing the bolt the rails and chair may be removedwithout the necessitjT of disturbing the fishing as will now be morefully described.

The chair B, is seen in section in Fig. 3, and is made with a single lipC, and a bolt hole f, as seen in Fig. il.

The rail joint is caused to fall between the sleepers, the chair beingsupported by a bridge I, formed of plank of suitable thickness which issecured at each end to the sleepers D. The fishing piece E, which isspiked down through this plank permanently to the sleepers has a rabbetcut in its under surface to accommodate the chair as seen at i, (Fig. 2)and a hole to receive the bolt H, which passes down through the fishing,through a notch in the hase of' the rail, and through the chair and thebridge I, beneath which it is secured by the nut K. It is obvious thatthis single bolt in connection with the single lipped chair and thepermanent fishing piece holds the adjacent ends of the rails in placeand that on the bolt H, being removed the chair may be knocked out andthe rails set free.

Among the advantages arising from the above described arrangement ofchair and fish piece may be enumerated the following: First, the elasticbed thus afforded to the chair saves the ends of the rails which are nolonger battered and destroyed by the hammering of the wheels; second,the vertical displacement of the ends of the rails caused by the heavingor sinking of a single tie is but half what it would be were the jointchair placed immediately over the sleeper; third, the rails may beremoved without disturbing the fishing by simply withdrawing the bolt H;fourth, the rails will not creep as the bolt H, passes through a notchin the base of the rail; fifth, there is no rocking of the joint tie toraise and depress the ends of the rails and expose them to the blows ofthe passing wheels; sixth, it costs no more than the ordinary cast ironchair while it is easier taken care of and not so liable to get out ofrepair.

Vhat I claim as my invention and desire to secure by Letters Patent is-The one lip chair, secured by the single bolt, in combination with thepermanent fishing piece arranged and Operating in the manner set forthfor the purpose specified.
